To all whom it may concern:

Be it known that I, GEORGE ELNOBLE, of Lowell, in the county of Middlesex and Gom monwealth of Massachusetts, have invented certain Improvements in Spinning-Spindles, which improvements are fully set forth in `the following specicatiomreference vbeing had to the accompanying drawings.

My invention consists, first, iu the combination of the cover provided with a stud and an oil-hole, the lock-plate, and the shell provided with a vertical slot, to keep dust out of the step; second. in the spinning-tube, tapering upward exteriorly and downward interiorly, and provided witha whirl and bearingplug, said tube being adapted to enter the quill and to support and rotateit by frictional contact; third, in the quill provided with a central pin to strengthen'the same; fourth, in the combination, with the shell provided with horizontal and vertical slots,roi` the lock-plate provided with ears, and the spinning-tube provided with a shoulder, to prevent said tube from being accidentally removed in dofling.

Figure 1 is a genera-l section of my invention. Fig. 2 represents the stud provided with oil-groovesl and the step. Fig. 3 is' a section on the line A B in Fig. l, and Fig. Lis a section 011 the line (l D in Fig. l.

shank which enters a supporting-rail, and is secured by a nut, X, on the vunder side of said rail. E is around stud, imperceptibly tapered atthe lower end and securely driven into and through the bottom of the shell U and its shank.

A spinning-tube, H, surrounds the stud, its lower end being conical and resting slightly `on the step V. This step is daring and sur-r rounds the stud. One or more inletholes, W W', admit the Oilin the shell U into the step. A lock-plate, T, .(see Fig, 4,) being almost a flat ring, but open on one side enough to admit the spinning-tube H above the shoulder d, and having two ears, Z Z, on its opposite ed ges, is passed onto said tubey above' said shoulder and turned until said ears drop into slots Y, Fig. 3, on opposite sides of the top of the shell U. The slots Y extend only partly through the sides of the shell and open into others, M M, parallel to the top of said shell,

Uis a cylindrical shell, havinga cylindrical Y so that the plate T, being dropped linto the shell and slightly' turned,prevents the tube H from being raised from the stud E.

A circular cover, R, has a circular opening 4in the center large enough to admit the shoulder d, and has an annular flange on its under side, which lits the open top of the shell U, and has also a stud, l, on its under side, which lits either slot Y, and which stud, being placed in one of said slots, prevents the cover from turning.

The cover being lifted and turned, oil may be poured into the shell through the oil-hole S and the vopen side of the lock-plate T; but when the cover is replaced the oil-hole S will not be over said open side of said plate T, and there beingashoulder on the tube H at the top of said cover, filling the opening in said cover, the shell is completely covered and no dust can enter it.

The tube H is revolved by a whirl, G, and band, as the spindle in a ring-spinning machine is revolved. Above the whirl the tube H is gradually tapered to its top. A plug, F, placed about midway between the whirl and the top ot' the tube H, forms the upper bearing for the tube, said plug resting upon the top of the stud E, which is here conical and ts a hole of the same shape in said plug.

The tube H bears only upon the top ot' the stud and upon the step V, (not touching the lock-plate or the cover,) these parts centering it accurately.

To lubricate the top ofthe stud, the groove ais cut inthe stud from the step V, in the direction of the revolution of the tube H, halt'- way around the stud and to the top of the stud, and the revolution of the tube raises the oil in this groove. The oil, when the tube H isrevolved,y is carried up the groove a so rapidly as to press between the top of the stud E and the tube H, and thereby lifts the tube, bringing the shoulder d against' the lockplate. Therefore, another groove, b, running from end to end of the groove a, is cut halt' around said stud in the opposite direction, andreturns the surplus oil to the step V.

From the plug F the inner diameter of the tube gradually increases to the top of the tube. The insideof the bobbin or quill K tapers to tit the outside of the tube, and the quill also IOO has a pin, N, the upper end of which is fast to the quill, and the lower end of which tapers downward and enters the top of the spinningtube, so that the quill is very firmly held on the tube.

The pin N, if of nietal,shonld he hollow, to secure lightness, but, if of wood, may be solid.

The stud E should he made of hardened steel, and the step V and plug; F should be of such metal or alloy as will cause least friction.

The advantages of my invention are, that the quill not only embraces the tube, but the tube embraces a part of the quill; that the pin in the quill strengthens it against a crushing force, and that the pin N, being a separate piece from the quill, prevents the latter' from warping in the middle, (a frequent occurrence in ordinary quills,) and that, too, even where the pin is of Wood, as it is almost impossible that the grain of the wood in both pin and quill should be the saine.

The grooves a b may be out on the inside of the tube H.

I claim as my inventionl. The combination of the cover R, provided with the stud I and oil-hole S, the look-plate T, and the shell U, provided with the slots Y, as and for the purpose specified.

2. The spinning-tube H, tapering upward exteriorly and downward interiorly, and provided with a whirl, G, and bearing-plug F, said tube being adapted to enter the quill and to support and rotate it by frictional Contact, substantially as described.

3. The quill K, provided with the pin N, as and for the purpose specified.

4. In combination with the shell U, provided with the slots Y M, the lock-plate T, provided with ears Z Z, and the tube H, provided with the shoulder d, as and for the purpose speoilied.
